Abstract
En 中文
• HiFi-DC refines a frozen diffusion prior for zero-shot depth completion. • In-loop WLS anchoring enforces metric consistency during denoising. • Convergence-aware normal guidance improves fine structural recovery. • Strong gains are obtained on synthetic datasets with reliable ground truth. • Real-data analysis reveals sensitivity to sparse and imperfect boundaries.
